Dual-view image device for monitoring heat source and image processing method thereof

A dual-view image device for monitoring a heat source includes a first thermal image sensor, a second thermal image sensor, a driver, and a processor. The first thermal image sensor is configured to capture a first thermal image having a heat source in a first viewing angle. The second thermal image sensor is configured to capture a second thermal image having the heat source in a second viewing angle. The second viewing angle is smaller than the first viewing angle, and the pixels occupied by the heat source in the first thermal image are fewer than the pixels occupied by the heat source in the second thermal image. The driver is configured to drive the first and the second thermal image sensors to track the heat source and position the heat source within the first and the second viewing angle. The processor is configured to combine the first and the second thermal images into a dual-view image and output the dual-view image with the heat source.
